crab zosui rice soup

my friend had a post thanksgiving crab feast at her place and we went home with one crab.  i decided to make a crab porridge with it that i had at a japanese restaurant.  ours was more of a porridge and less of a rice soup but delicious and satisfying anyways.  it was combination of this recipe and this recipe

• cup of short-grain Japonica rice
• 7 cups of dashi soup stock, or chicken stock (you can use cubes or granules for either)
• 2 eggs
• 2 cups of fresh spinach leaves, washed (you can substitute other greens, such as bok choi leaves, Swiss chard leaves, etc.)
• 1 cup of crabmeat, or cut-up chicken breast, or imitation crabsticks (optional)
• 1 handful of flatleaf parsley leaves, or chervil, or (if you can get it) mitsuba (a kind of Japanese herb), or fresh coriander (Note: coriander would make this taste very not-Japanese, but that's ok. Mitsuba would be the most Japanese-tasting but is hard to get unless you grow your own.)
• Salt, white pepper, soy sauce

Wash the rice following the instructions for plain rice. Put the rice in the stock, heat up and then cook over low heat, stirring occasionally, until the rice is tender.
In the meantime, blanch the greens in a pot of boiling water. (Blanching means to cook for a few seconds in the boiling water.)
Add the seafood or chicken to the rice soup, and stir until just cooked through. Add the blanched greens.
Whisk the eggs into the soup, stirring all the time. The eggs should form into sort of soft strings throughout the soup.
Taste the soup and adjust the seasoning with salt, pepper and soy sauce. You may wish to add some Japanese chili powder (Ichimi tohgarashi, or Shichimi tohgarashi - look for these at Japanese food stores).
Garnish with the herb leaves. Serve piping hot.
